Specification of Letters Patent.

SYRACUSE, NEW YORK, A CORPORATION OF NEW BUSHING- Pat ented May 29, 1906.

Application filed August 21, 1905. Serial No. 275.092.

with the accompanying drawings, is a full,

clear, and exact description.

This invention relates to im rovements in bushings, and particularly spllt bushings for loose pulleys or for ournal-bearings in which it is desired to provide a wearing surface or bearing made up of laminations arranged side by side throughout the length of the hearing so that the edges of'the laminations are presented to the shaft.

My object is to incase these laminations in a comparatively inexpensive sheet metal housing which may be stamped or pressed in the form of semicylindrical sections, each made of a single piece having its ends crimped inwardly and firmly against the end faces of the laminated inner cylinder.

In the drawings, Figure 1 is a perspective view of a split bushing embodying the features of my invention. Fig. 2 is an inner face view of one ofthe half-sections of the bushing, showing one end of the outer shell as crimped or turned inwardly against the end face of the laminated cylinder, while the other end of said section is shown as extended rior to being'crimped.

his bushing comprises two opposite semicylindrical sections, each composed of an inner semicylinder 1 of hide, vulcanized'fiber, or any other similar cheap material which is capable of affording a certain degree of lubrication, either by absorbing and retainin the lubricant, as might be done with wood, her, or similar absorbent, or it might be made of hide, which contains its own lubricant. This inner semicylinder is made of a series of semicircular strips or disks pressed together face to face and incased 1n a semicylindrical metal sleeve-section 2, which fits snugly upon the periphery of the section 1 and has its opposite ends crimped or bent inwardly at 3 against the opposite ends of the sectlon 1 to firmly bind or retain the laminations in operative position. In order that these inturned edges may lie in substantially the same lane when turned over or inwardly, I provi e the ends witha series of V-shaped cut-outs 4, and

the inturned edges are made of less radial projection than the thickness of the laminations 1, so that the inner edges of the 1n- ,turned flanges 3 terminate short of the inner bearing-face of the cylinder 1. These laminations may be compressed in the same operation of turning or crimping the flanges 3 inwardly, or the several strips may be first compressed into the desired form and then retained by the outer metal casing 2 and flanges 3.

What I claim is 1. A bushing comprising inner semicylindrical sections, and outer semicylindrical casing-sections having their end edges crimped or bent inwardly against the ends of the inner semicylindrical sections. 2. A split bushing comprising mner semlcylinders each composed of semicircular laminations pressed together face to face, and semicylindrical casing-sections of sheet metal inclosing said inner sections and havlng thelr ends crimped or bent inwardly upon the end.

faces of the inner sections. I

In Witness whereof I have hereunto set my hand this 12th day of August, 1905.
